SIGHT FOR FlREd-ARMS.

SPECIFICATION forming part of Letters Patent No. 259,844, dated June 20,1882.

Application inea March 1,1882. (Modem To all whom 'it may concern Be itknown that I, FREDERIC J. GARDNER, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Rifle-Sights, of which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings,formin gapartof thisspecication, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l represents a view in perspective of a rie, in part, with myimproved front and rear sights applied. Fig. 2 is an end view of anouter tube used in the front sight, and Fig. 3 is a longitudinal sectionthereof. Fig. 4 is l alongitudinal section of an inner tube used in theconstruction of the front sight, and Fig. 5 is a rear end View of thesame. Fig. 6 is a face view of the rear sight; Fig. 7, a transversesection of said sight on the line a x in Fig. 6, and Fig. S alongitudinal vertical section thereof.

The several gures from 2 to 8, inclusive, are all upon a larger scalethan Fig. l.

This improved rifle-sight is more particularly intended to be used fortarget-practice; and it consists of both a front sight and rear sight ofpeculiar and advantageous construction, the fore or front sight beingopaque, of tubular construction, with a transparent cross plate or diskof glass having a sight-hole in it, and the rear sight comprising atransverselyslotted body and a transversely adjustable cross-slideprovided with a sight-hole Within range of the slot in the body of therear sight, substantially as hereinafter described.

The front sight, A, (represented in the drawings,) comprises a fixedouter tube, b,of metal or other suitable opaque material, arranged inlongitudinal direction with the barrel of the rifle, and an innertube,c, tted to slide within the outer tube, and removable therefrom whenrequired. Both of these tubes are open at their ends, and the inner one,c, is provided with a cross disk or piece, d, of plain glass, having acentral sight-hole, c, in it. This glazed front sight does not obstructany part of the target, and, when properly held, admits of the bulls-eyebeing very distinctly seen through the hole c in the glass. Said glassneither iucreases nor diminishes the size of the bullseye, and thereforedoes not aifect the eyes; neither does it make an object appear to befarther away than it reallyY is, which is a distinguishing feature of itas compared with other sights; nor yet does it cause that gloom aboutthe bulls-eye which is so common to other sights when held directly onsaid mark.

The hole c in the glass may be of any size or diameter desired, or, inother Words, can be made to suit any focus at any range.

By setting the glass d in the inner tube, c, which maybe slid or drawnout from the outer tube, b, every facility is afforded for cleaning theglass, and such inner tube may be readily reset or replaced. Said innertube, c, also acts as a gage for shading the face ofthe glass, and canbe adjusted longitudinally or drawn back and forth at pleasure of theoperator.

The rear sight, B, which may be used to advantage in connection with theimproved front sight just described, is composed in part of a disk orplate of metal, f, mounted on a screw, g, for regulating the height ofthe sight. This plate fforms what maybe termed the body 7 of the sight,and has an oblong horizontal slot, h, through it, which slot is coveredon the back side of the plate f with a sighting-slide, t', having asight-hole, 7c, in it, and fitted to slide in direction of the length ofsaid slot to adapt the sight to variations in wind or weather. rIhesight-hole 7c is made in or through a forwardly-projecting shank, whichis fast to the slide 'i and forms the bearing for the slide in thesloth. This shank is of tubular construction where it projects in frontof the sight, and such front projection is cut away underneath, so as toform a half or partial tube, m, which acts as a shade for the sight-holek, or opening in the back of the rear sight. Fitted to turn freely onthis shank or part tube m,.be tween a collar thereon and the face sideof the plate f, is an adjusting or second plate, n, of eccentricconstruction. This eccentric plate n is provided with two projections orlingerpieces, o 0,0n its face, which projections serve for turning theeccentric by the thumb and forenger, in order to adj ust the slideacross the plate f, said eccentric being held in position by or workingagainst guards or springs r 1' upon the plate j. This forms an easy andeffective means of adj ustin g the sighting-slide. Having thus describedmyinvention, I claim as new and desire to secure byLetters Patent- 1. Atubular front sight of opaque material, fitted with a transparent crossplate or disk of glass having a central sight-hole,substantialy asspecified.

2. A front sight for rides and other guns, o opaque tubularconstruction, composed of an outer xed tube and an inner slide or tubeprovided with a transparent cross plate or disk of glass having acentral sight-hole in it, essentially as shown and described.

3. The combination of the eccentric n, the slotted plate or sight-bodyf', the adjustable cross-slide t', having a sight-hole, k, the partialtube m, the projections or linger-pieces o o,

and the guards or springs r 1', essentially as zo herein described.
